Engineered for precision internal threading, Carmex's carbide thread mill combines a single-point design with MT11 taper to deliver crisp, accurate threads in ACME and other common internal-thread forms. This tool is built for machinists who demand consistency, durability, and clean finishes on metal parts.

• Thread mill type: Full-profile, carbide single-point thread mill designed for cutting internal threads with stable geometry across passes.
• Thread forms supported: Capable of producing internal threads including ISO M1 x 0.25 up to 0-80 UNF.
• Depth capability: Thread depth can reach up to 3.5 times the thread diameter, depending on the profile and application.
• Flute count: Multi-flute design (3–4 flutes) for balanced rigidity, smooth entry, and efficient chip evacuation.
• Material and coating: Solid carbide core with MT11 Ultra-fine sub-micron grade and triple blue PVD coating for enhanced wear resistance and tool life.
• Size and interface: 5/8" diameter with an 8 x 8 footprint and MT11 taper for compatibility with common milling setups.

This thread mill helps you achieve reliable internal threads with excellent surface finish, even in challenging materials. The combination of a fine-grain carbide core and the advanced PVD coating reduces wear, extends tool life, and supports repeatable tolerances. The 3–4 flute geometry offers robust stability and effective debris evacuation, which translates to cleaner threads and fewer reworks. Whether you’re prototyping or producing parts, this tool is suited for precision work in mechanical assemblies, lead screws, and threaded components that require consistent internal threading performance.
